LAS'TING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 443,351, dated December23, 1890.

Application filed January 3, 1890. Serial No. 335,795. (No model.)

To all whom it may concern:

Be it known that I, SETH BRAGGINS, a citi- Zen of the United States,residing at Rochester, in the county of Monroe and State of New York,have invented certain new and useful Improvements in Lasting-Machines,of which the-following is a specification.

My invention relates to lasting-machines, and is designed, primarily, asan improvement upon the machine for which Letters Patent No. 387,366were issued to Seth W. Paine, Hiram A. Gray, and Charles E. PetteeAugust 7, 1888.

In the drawings, Figure 1 is a side view of so much of a lasting-machineas is necessary to illustrate my invention;' Fig. 2, a perspective viewof a portion of the machine; Fig. 3, a Vertical sectional view throughthe back plate of the machine; Fig. 4, a rear face View; Fig. 5, asectional view on the line 5 5 of Fig. 4; Figs. 6 and 7, respectively,perspective and sectional views of the heel-wipers; Figs. 8, 9, and 10,views illustrating the construction of the devices for supporting thetoe-wipers; Figs. 11 and 12, views showing the construction of thesupport for the heel-wipers; Figs. 13 and 14, views showing theconstruction of the supports for the side lasting-jaws; Figs. 15 and 16,sectional views of the last-supporting arm; Fig. 17, a View of one ofthe side lasting-jaws with the end former partly in section; Fig. 18, aface view of the end former, and Fig. 19 a sectional view of the stockor head carrying the toe-pinchers.

A indicates a metallic frame supported by legs B, and comprising ahorizontal bed portion 0, an upright back plate D, and an overarchingarm E, arranged substantially as in the patent above referred to.

The back plate D is provided with a vertical slot F and with horizontalways or guides G G, Figs. 1, 2, and 3, the former adapted to receive thelast-support H, and'the supports I and J for the toe and heel lastingdevices, while the guides or ways G receive the supports K K for theside lasting-jaws.

The supports K K are duplicates, and hence a description of one will beapplicable to both. These supports comprise each a flat plate K to fitinto the ways or guides G and a hollow arm K to receive a stem K(preferably cylindrical,) having at its outer end an eye K to receivethe stem of the jaw, as shown in Figs. 1, 2, 13, and 14. Upon the underside of arm K are lugs K K in which is mounted a rod or stem K, the stemturning freely in one of the lugs, but being threaded to engage with theother lug, through which it passes, as shown in Fig. 14. Between thelugs K the screw-stem K is provided with a knurled collar K or othermeans by which it may be turned.

The stem K is provided with a perforated lug K to receive the outer endof the screw K, the lug being embraced between collars upon the stem, soas to prevent longitudinal movement of the latter through the lug, butpermitting it to turn freely therein.

From the foregoing it will be seen that by turning the screw-stem K thestem K carrying the jaw may be adjusted so as to bring the fingers 0rblades of the jaw into the same plane a with the bottom of the last. Inorder to clamp the jaw-stem in the eye K of the stem K a screw K istapped into the body of the eye adjacent to its opening, and the saidscrew is encircled by a collar K which intersects the opening or bore ofthe eye K as shown in Figs. 13 and 1 1, so that when the screw is turnedin one direction it will cause the collar to bear firmly against theshank of the jaw, and thereby firmly clamp the jaw in position.

Screwing into the back of the plate K of the support K is a stud or pinK, for a purpose presently explained, the back plate D being slotted, asat K Fig. 4, to receive and permit the studs to slide horizontally withthe supports.

The heel-former carrier J, Figs. 1, 2, 3, 11, and 12, resembles somewhatthe supports K for the side jawsthat is to say, it is provided with ahollow arm to receive a stem or shank, which in turn receives theheel-lasting devices, and it is also provided with a screw for adjustingthe said lasting devices toward and from or relatively to the bottom orheel of the last, and hence these parts need not be described.

The support J is provided with a body portion J, designed to slide inthe vertical slot F in the back plate D, the said body portion beingcored out to receive a block or nut J having a lateral arm or lug Jwhich proj ects outward through a slot J in the rear face of the supportand through a slot 5 in a plate J, secured to the support, as shown inFigs. 3, 11, and 12. This plate,in conjunction with the flanges J formedon the body of the carrier or support J, holds or clamps the latter tothe upright plate D. Within the block or nut J is a sleeve or tube Jthreaded externally to engage the nut and prevented from longitudinalmovement within the support or carrier J by means of collars or washersJ" and screws J", or in any other suitable man ner.

.1, Figs. Sand 12, indicates a screw carried by the sleeve or tube, thereduced end of the screw projecting into the interior of the sleeve toengage a slotted shaft I, for a purpose presently explained.

The support or carrier I, Figs. 1, 2, 3, S, and 9, for the toe-lastingmechanism comprises a body portion 1 to fit into the slot F in theupright plate D, a hollow arm l to receive the stem or shank Lof theframe or head L, that carries the toe-wipers, and finally a secondhollow arm I to receive the support 0 for the toe of the last,theinnerend of the arm I bein g set away from the front face of the bodyportion 1, as shown in Figs. 1, 3, and 8, and provided on its side witha bracket 1*. Secured to and projecting from the rear face of the bodyportion 1, or the plate M carried thereby, is a stud 1, upon which ismounted a plate or disk I, having a handle or lever 1 as shown in Figs.3 and l. A link I connects the cam-disk with the stud I", secured to thelug or arm J of the support J, while links I I connect the plate or diskwith thejaw-supports K K, as indicated in Fig. l.

L, Figs. 8 and 9, indicates the toe-pinchers head provided with a hollowstem L to lit within the hollow arm I and with separated arms L Lcarrying a pin L upon which a tubular case or shell L is adapted toswing. The stem L is guided in its movements bya spline or feather L,Fig. 8, and projecting from the upper face of the stem is a stud L,which works through a slot L in the hollow arm 1 This stud L isconnected with the upper end of the casing L by an extensible andyielding connection L comprising two rods L L, a large handnut L, havinga socket to receive a spring L and screwing onto the end of one of therods L, a flanged nutL, screwing onto the end of the other rod L andbearing on the spring, and finally a hollow nut L flthrougli which nut Lslides freely, screwing into the hand-nut 1 as shown in Fig. 8. Fromthis construction it is clear that the head or case L" may tip or rockupon its pivot L, and that in thus rocking or tipping the spring L willyield or be compressed slightly in order that the toewipers (not shown)carried by the case or shell L may adjust themselves automatically tothe bottom of the last in case the latter should not be in line with thetoewipers. It will also be noted that by turning the handnut L in one orthe other direction the case or shell L and the wipers carried therebymay be given any desired inclination to correspond with the longitudinalcurvature of the toe portion of the last.

Sliding in the shell or casing L" is the stock or shank that carries thetoe-wipers, the stock consisting merely of a straight rack-bar M,provided on one face with teeth, with which a pinion M, Figs. 8 and 9,mounted loosely on the pin L engages. The hub of pinion M is elongatedto receive or is provided with a bevel-gear M Figs. 8 and 9, whichlatter meshes with a similar gear M on the end of a shaft M, extendingcentrally through the hollow stem L, so that as the shaft M is retatedthe rack-barM, to which the toe-wipers are attached, will be projectedfrom or withdrawn into the case or shell L. The shaft M" is designed toslide lengthwise with the head L, and to provide for this movement therear end of the shaft is passed through a bushing M, which is carried byor journaled in the plate M, that clamps the support I to the back plate1). A spline or feather M Fig. 4, permits the shaft to move lengthwisethrough the bushing, but prevents these parts from turning independentlyof each other.

Encircling or secured to the bushing M is a crank-arm M Figs. 1 and 4,which is connected with the cam-plate by means of a rod or pitman M".The head L is formed or pro vided with an upright plate M on one side,having a curved slot M, Fig. 3, concentric with pin L, to receive one ormore studs M projecting from the side of the shell or easing L, the saidstuds or screws M carrying a plate M having a line or mark thereon,which in connection with the marks or graduations on the plate M enablesthe operator to tell at a glance whether or not the head L is at theproper inclination.

Projecting from the side of the hollow stem L is a lug N, which isthreaded to receive a hollow sleeve or nut N, which latter in turnreceives a shouldered rod N carryinga block N to work in a pivotedguide-plate N, secured to the back plate D, as shown in Figs. 2 and 10.Plate N" is secured to plate D by means of a screw l\" in such manner asto permit its inclination to be varied as desired, the plate beingprovided with a curved slot N to receive a screw N, by which the platemay be clamped in different positions. If this plate N be arranged in aninclined position and the support I be raised, the block N working inthe guide-plate N", will, acting through the connections N, N, and N,draw the head L and attached parts inward within the hollow arm 1 andwhen the support I is lowered the head L will be projected. By varyingthe inclination of the plate N the degree and direction of the automaticmovement of thehead L may be conthereof by turning the nut N, which isheldagainst longitudinal movement upon the rod N by the means shown inFig. 9.

In the hollow arm I of the support I is mounted a rod or stem 0 (shownin Fig. 8) to receive the rest for the toe of the last, the stem or rodbeing urged outward by'a spring 0' and guided in its movements by a pin0 At its inner end the rod 0 is loosely connected with an arm 0 securedupon the upper end of an upright shaft 0 which latter is supported atsaid upper end of the bracket 1 projecting from the side of the supportI. This shaft 0 passes vertically through the last-support H and isstepped at the lower end in a plate 0 which will be secured in properposition upon the floor, as in Figs. 1 and 3.

In the plate or bracket 0 is mounted a foottreadle O, to the shaft oraxis of which is secured a bevel-gear 0 adapted to mesh with a similargear 0 secured to the shaft 0 so that when the treadle is depressed theshaft will be partly rotated, but when the foot is removed the springs Oand H will return the parts to their positions.

The last-support H comprises a hollow arm II and a main body H to workin the slotted back plate D, as shown in Figs. 2, 3, 15, and 16. Mountedand free to slide in the arm II is a rod or stem H to receive the last,the rod being urged outward by a spring H seated in the arm andconnected with an arm H secured to the shaft 0*. Of course when theshaft 0 is rotated, as above described, its arms 0 and II will draw thestems or rods 0 and H inward into their respective arms I and H and willcarry the last with them.

P, Fig. 4, indicates a shaft bearing at one end a bevel'wheel P and atthe other end a handle P the shaft being mounted in a sleeve P securedto the under side of the bed in line with the upright back plate D. Thepinion P meshes with a similar pinion P on the lower end of a shaft Pwhich latter is journaled in the base-plate C, as shown in Fig. 1. Thisshaft P is provided with right and left threaded portions P and P ofdifferent pitch, which engage, respectively, with the supports orcarriers H and I. The

' shaft is also grooved longitudinally, as at P sleeve J but as thelatter is prevented from moving endwise within the support J therotation of the sleeve within the block J 2 will cause the latter torise or fall, according to the direction of rotation. As the block ornut J 2' is connected with the cam-disk I by means of the link 1 itwill, in being thus raised, turn or move the said disk slightly andcause the latter, through the links 1", to move the jaw-supports K Kinward toward each other. These supports K are adjustably connected withthe links 1 so that the inward movement may be compensated for. Theturning of the screw-shaft to the right will raise the last-support IIand lower the toe-lasting support or carrier I simultaneously with theraising of the block J of the support J. The threads on the shaft andthe sleeve vary in pitch in the proportions nine, twelve, and five, sothat the block or nut J will move upward farther than the support II,while the support I will move downward slower than the support H movesupward. In order that the adj ustments of the supports may not affectthe operation of the treadle-shaft 0 the latter is made telescopic, asshown in Fig. 3. In order to vary the adjustment of the side jaws tocause one set of fingers to act in advance of the other set, or for anyother reason, the stud K of each support K receives an eccentric flangedcollar Q and a stud or screw Q, that is connected by the link I with thecamplate, as shown in Figs. iand 5, the collar being free to turn on thescrew or stud K except when held against turning by means of thespring-pin Q This spring-pin is carried by the head or enlargement ofthe link I and is adapted to engage with any one of a series of holes orperforations Q made in the flange of the collar. \Vhen the pin iswithdrawn, the collar is free to be turned, and as a consequence thejaw-support will be moved toward or away from the center of thecam-disk, according to the direction in which the collar is turned.

RR, Figs. 1, 2, and 3, indicate arms or brackets, that projectfrom thesides of the shell or casing L and carry the toe-pinchers heads R R, thearm or bracket of each head serving not only as a support for thelatter, but also as the axis of a sector-shaped rack R Fig. 19, whichengages with the toothed hollow sleeve R which is designed to worklongitudinally through the head R. The sleeve is guided in its movementsby a set-screw R (shown in dotted lines in Fig. 19) and carries thepinchers-holder R, which latter is adjustably mounted in the sleeve. Theupper end'of the holder is threaded to receive a nut R, fitting into theend of the sleeve, a spring R" encircling the shouldered holder R andbearing against the nut and the case or shell, as shown. If the strainon the leather should be too great, the spring will be compressed, so asto permit the hollow sleeve R to move upon the holder S, Figs. 1 and 2,indicates a shaft journaled upon the under side of the overarching arm Eand provided with a hand-lever S and two arms S S the said arms beingconnected by an adjustable connecting-rod S with the arm of thesector-shaped wheel R '1, Fig. 1, indicates a second shaft, alsojournaled upon the under side of the arm I and provided with arms T anda handle or lever T the arms T being connected by extensible rods orconnections T with the operating lover or block of the pinchers carriedby the head R, substantially as in the patent before referred to.

The side lasting-jaws comprise a main body U, a series of longitudinalfingers 1'', a former U to bear upon the backs of and to give the propercurvature to the row or line of fingers, and an end former U, having ateach end a slot U as shown in Figs. 1, 17, and 18. The slots in theformer U are each enlarged at their upper ends, so as to fit over theheads of pins or studs 'U, projecting from the outer face of the jaws,the pins being reduced in size immediately below the head, so that whenthe former is slipped onto or over the pins or studs and then movedlengthwise it will be etfeetually prevented from becoming accidentallydetached. No broad claim is in tended to be made herein to an endformer.

Fitting in the support J is a hollow stem V, Figs. 1, 2, 3, l1, and 12,which receives the shank V of the heel-wiper, the stem V being providedwith a spring-catch V to engage with or enter a notch in the body V ofthe wiper. As shown in Figs. (3 and '7, the body V comprises a back andsides and an open front and top, and hung or pivoted between the sidesis ablock V, the pin Y, upon which the block swings, being mounted inslots in the sides of the body, so as to permit the block, with itspivot or pin, to move bodily back and forth relatively to the body V.

indicates a stem or rod projecting from the back of the block throughthe back of the body V and encircled by a spring V, bearing against thebody and a nut on the stem, the rod V being carried by the pin V, beforereferred to. A set-screw V at the upper end of the body Y limits theinward movement of the block Pivotally secured to the upper end of theblock Von its front. face are the blades or wipers V Y.

It is of course to be understood that the machine will be provided withpinchers for stretching the upper upon the last, as in the patent abovementioned; but as they form no part of the present invention they arenot shown or described herein.

Secured to the upright plate I) is a scaleplate I), over which a pointerD carried by the support I, is designed to move, as shown in Fig. 2, sothat the operator may see at a glance how far to turn the screw to adaptthe machine to different-sized lasts.
